Here it is!
Tweeted by avid Fortnite data miner iFireMonkey, we are able to see a closer image of the Herald.
iFireMonkey also noted the following caption with this photo:
"The Herald has found The Island. The prelude to War has begun."
WOW - Could we see a war?
Fortnite themselves followed with confirmation that this is the second teaser for the new season!
Along with the above teaser which has confirmed there will be some sort of war between Thor and Galactus.
They have also activated the in-game rifts above Catty Corner as noted by iFireMonkey!
We can assume this is where Thor and Galactus are going to appear when they eventually begin battle on the map!
